Filed Oct. 13, 1950 gwwntoz- Patented July 19, 1932 PATENT ANTHONY COVIELLO, 01? DENVER, COLORADO LAWN SPRINKLER Application filed October 13, 1930. Serial No. 488,343.

This invention relates to improvements in sprinkling nozzles for use with garden hose and has special reference to a nozzle, or sprinkler, that is specially well adapted for use in sprinkling parkings and other limited spaces.

It is well known to those who maintain lawns that the ordinary nozzles, or sprinklers used, for irrigating lawns are unsatisfactory n for the reason that the majority of them throw a circular spray or an oblong one, and, therefore, when they are used adjacent to sidewalks and curbing a large amount of the water is wasted by being thrown onto the i5 sidewalk or into the street, and besides the wasting of the water pedestrians are usually greatly inconvenienced where the spray extends over and onto the sidewalk.

In sprinkling adjacent the sides of houses and along fences, the ordinary sprinkler is also objectionable for reasons similar to those pointed out above.

It is the object of this invention to produce a nozzle of simple and substantial construction that shall be so made that it will throw an elongated spray to one or both sides of the sprinkler, and which shall be provided with means for limiting the lateral projection of the water in such a way that when it is placed adjacent to a sidewalk or a curbing or to the side of a house, the water will be distributed over an area having substantially parallel sides in such a way that very little of the water will be projected beyond the area that is to be irrigated,

The above and other objects that may appear as the description proceeds are attained by the means of a construction and an arrangement of parts that will now be described in detail, and for this purpose reference will be had to the accompanying drawing in which the preferred embodiment of the invention has been illustrated and in which:

Fig. 1 is a plan view of my improved sprinkler, showing the same attached to the end of a hose.

Fig. 2 is a section taken on line 22, Fig. 1.

Fig. 8 is a section taken on line 3-3, Fig. 2.

Fig. 4 is a section similar to that shown in Fig. 2, but showing only a portion of the sprinkler, this view shows a slightly modified form of construction, and

F 1g. 5 1s a plan view showing a portlon of a parking with my sprinkler in place thereon. V In the drawing numeral 1 indicates an ordinary garden hose provided at its end with a coupling 2. Secured to the coupling is my improved sprinkler which has been designated in its entirety by reference numeral 3.

The sprinkler consists of a cylindrical body portion 4: that is provided on opposite sides with laterally extending arms 5 that serve as a base for the sprinkler. The under surface of the base is preferably slightly concave as shown in F 2, and when the sprinkler is cast, the base may be recessed as indicated by reference numeral 6 so as to reduce the amount of material. One end of the cylindrical body is preferably on a line with the corresponding side of the base, while the other end, which has been designated by reference numeral 7 extends to one side of the base as shown in Fig. 3. Extending inwardly from the end designated by reference numeral 7 is an opening 8 comprising two cylindrical sections of different diameters. The outer section, which is the larger, is provided with threads 9 that extend inwardly a short distance and which serve as a means for con necting it to a hose. A washer 10 is located adjacent the shoulder formed between the two sections of the opening. Extending transversely through the body member adjacent the top of the opening is an opening of smaller diameter, which has been designated by reference numeral 11. This opening is preferably parallel to the bottom of the base, and extends entirely through the body member as shown in Fig. 2.

Secured to the upper surfaces of the arms 5, are deflector plates 12. These deflector plates are provided with base portions 18 that fit against the upper surfaces of the arms 5, and are secured to the latter by means of rivets 14L. The inner surfaces of the deflector plates are slightly concave as indicated by reference numeral 15, and are so located with respect to the opening 11 that the streams of water that emerge from the opposite ends of opening 11 strike the concave portions of the deflector plates at an angle, thereby causing the water to be deflected upwardly and laterally in the manner indicated in Fig. 5. The water that is projected upwardly ascends at a steep angle, and, therefore, does not go very far outwardly, whereas the water that is pro jected from the sides and upper corners of the deflector plates travels at an angle with respect to both the axis of the sprinkler and the surface of the ground, and, therefore, travels much farther before reaching the ground with the result that the water is distributed over an area that is much longer than it is wide, and, therefore, when the parts are properly adjusted and the sprinkler properly positioned on a parking, the entire width of the parking will be irrigated and only a small amount of water projected on to the sidewalk or into the street. When one section of parking has been irrigated, the water is turned off and the sprinkler moved a distance equal to the total length of the area that it irrigates, whereupon the water is again turned on and another section irrigated.

The width of the area that is irrigated is determined to a great extent by the inclination of the inner surfaces of the deflector plates with respect to the axis of opening 11, and when the deflector plates are secured to the sprinkler by means of rivets, as shown in Fig. 2, this angle is varied by bending the deflector plates outwardly or inwardly so as to get the desired distribution.

In Fig. i l have shown the deflector plates secured to the sprinkler by means of screws 16 that pass through elongated openings 1.? in the base portions 13 of the deflector plates. By loosening these screws, the plates can be moved inwardly or outwardly with respect to the body portion 3, and since the upper surfaces of arms 5 are curved conve'Xly and are downwardly and outwardly inclined, the angle between the deflecting surfaces and the axis of the stream of water is varied by moving the deflector plates, and, therefore, the lateral distribution of the water can be varied by moving the plates in the manner described.

It is sometimes desirable to have only one of the sprays operating at one time, and T have therefore provided a valve by means of which the discharge of water onto one of the deflector plates can be controlled. Referring to Fig. 2 it will be seen that in one side of V the body member an opening 18 has been provided, which intersects the opening 11 and which is of bigger diameter. Located within the opening 18 is a valve member 19 that is provided on one side with a notch 20 through which the water may pass when the valve member is turned into the position shown in Fig. 3. A spring 21 is located between the bottom of the opening 18 and the lower end of the valve member and tends to material 22 that surrounds the stem 23,'and

which is held in place by means of a nut 24:. The upper end of stem 23 has a transverse bar 25 by means of which the valve member can be rotated. When the valve member is turned 90 degrees from the position shown in Fig. 3, water will not flow outwardly through that end of the opening and the sprinkler will then have only a single spray which will adapt it for use along sides of buildings and along line fences and other places where the side of the area to be irrigated is bounded by a straight line or wall.

From the above description it will be seen that I have produced a lawn sprinkler that is so constructed that it will simultaneously irrigate two substantially similar areas located on opposite sides of the sprinkler, and which is also so constructed that each of the areas are substantially rectangular in shape whereby parkings or other surfaces bounded by straight lines can be quickly and conveniently irrigated with the least possible eX- penditure of time and trouble.

Having described the invention what is claimed as new is:

A sprinkler comprising an elongated base having a central enlarged portion having an opening extending into it from one side thereof, the wall of the opening having a threaded section adapted to make connection with a hose, the wall of the enlarged portion having two openings extending in opposite directions and whose axes are substantially parallel wth a plane contacting with the bottom of the base, a deflector located in front of each opening, said deflectors having base portions (13) which rest on the upper surface of the base and means for securing the deflectors to the base, those portions of the de flectors that are located directly in front of the openings being upwardly and outwardly inclined whereby the streams of water which issues from the openings will be deflected upwardly and outwardly on each side of the axis of the opening to which the hose is connected.

In testimony whereof I affix my signature.

ANTHONY COVIELLO.
